Silicon Image, Inc. (NASDAQ:SIMG) investors should pay attention to a decrease in enthusiasm from smart money in recent months.

To the average investor, there are a multitude of metrics shareholders can use to watch publicly traded companies. A couple of the most underrated are hedge fund and insider trading interest. At Insider Monkey, our research analyses have shown that, historically, those who follow the best picks of the top hedge fund managers can trounce the S&P 500 by a very impressive margin (see just how much).

Equally as beneficial, optimistic insider trading activity is a second way to break down the marketplace. Just as you’d expect, there are many stimuli for an insider to drop shares of his or her company, but only one, very obvious reason why they would buy. Various academic studies have demonstrated the useful potential of this method if shareholders understand what to do (learn more here).
